IP Addresses
FTOS supports IP version 4, as described in RFC 791. It also supports classful routing and Variable Length
Subnet Masks (VLSM). With VLSM one network can be can configured with different masks.
Supernetting, which increases the number of subnets, is also supported. Subnetting is when a mask is
added to the IP address to separate the network and host portions of the IP address.
At its most basic level, an IP address is 32-bits composed of network and host portions and represented in
dotted decimal format. For example,
00001010110101100101011110000011
is represented as 10.214.87.131.
